Step 2: Bottle Cap

Step 3: Label

Download the Quantum label from here: http://whatpayne.deviantart.com/art/Nuka-Cola-Quantum-label-106603029 I put it in word and after alot of trial and error finally got it the right dimensions. Print onto the glossy photo paper, ...

Step 5: Liquid inside

Step 6: The Science

Now the mixture glows because the tonic water contains small amounts of Quinine. Quinine fluoresces when exposed to ultra-violet light. Light is considered ultra violet when it has a wavelength lower than 400nm. ...

<p>An alternate idea for the light.... No fuss or tools needed. I use party balloon bullet led lights on a lot of my projects. They come in colors, but also white. Just twist it to turn on and off. About $1.25 each. Like the project!</p>

this is my version of the cola. it looks like orangejuce, but it glows!

<p>That looks so awesome! Good job! ;)</p>

<p>I tried this with a red LED and it didn't work too well.</p><p>Did you use tonic water for this, or something else?</p>

<p>Wow, nice job!</p>

RAD I like this a ton <br>well done

Thanks

Is it ok if i try and sell these to my friends? I will make sure they know i didnot design it or i could put a wacky alex sticker on base or somthing? Great instructable!

Sure! I would love a picture of the finished thing. The LED I used was a 5mm 2000mcd UV LED.

Oh yeah and what size led did you use so i can build a personal one?

This is great! Just wonder how a 15 year old can do this and a 68 year old can't even figure out what he's talking about. More power to you.

Thank you, I used Google extensively to find out what glows under what and why. Younger people have the advantage of finding technology easier to use as we've always had it.

I'm so going to make something similar to this for my brother :D <br>He loves fallout and so do I. <br>You, sir, are awesome.

Thanks looking forward to Fallout 4, aparrently its being set in Boston.

Oooh that sounds cool :O

All Fallout-based instructables earn my respect, especially ones that are well done. Great work!

Thanks, Fallout is one my favourite game series, looking forward to Fallout 4.

This is awesome! I love the Fallout games! Thanks for the instructable, I now know what I'm making for my brother when he gets back from boot camp!

Thanks, me too. I hope he likes it!

Fantastico y muy bien explicado!! Te felicito. Saludos desde Chile!!

Gracias, hago lo que puedo. Saludos desde Escocia!

Just a thought, coating the leads in silicone caulk would help in keeping them from getting wet and shorting out, wouldn't it? <br> <br>Cool instructable!

It would but it could make it look ugly and it doesn't short out for some reason. Apparently it's because the LED is more conductive than the water. <br> <br>Thanks for commenting!

This is a very well put together instructable! <br>I've been a member for some time, but your article has inspired me to give it a go! <br>

Thanks! <br>You really should, it's fun and very satisfying. It also makes a great conversation starter if you have new geek friends round.

The water is less conductive than the led

Thanks for the comment! I didn't know that. I just guessed.

Hey great instructable, but Im having one problem: the resistor and LED are bent in proper position around the battery, and even work when I squeeze them together on either side of the battery, but the magnets arent seeming to produce enough force on either side to get the LED to light up. Any suggestions?

I made the resistor leg into a square around the magnet to hold it and then used the one on top as a conductor between the LED leg and the battery. Here's some pictures. The cap is being used as a shade as it kept throwing the focus off.

Thanks! It works perfectly with that little adjustment. Now I just have to deal with the label and I have myself a finished project!

Nice one!

Nice! Wonder if a truly radioactive version could somehow be made using thorium mantles or old radium-painted clock hands? :-)

Well... If you get the radium off the clock hands, then you could combine it with some blue fluorescent powder to make it glow. I think that could make it glow. I do physics, they wouldn't let me do chemistry.

An easier way to make sure the label prints out exactly right would be to use photoshop or gimp (or some equivalent). open a new image and give it a working area of 9.7cm, then paste in the labels and resize to fit the whole image. print without stretching to fit and it should work fine right off the bat.

Ah, thanks. I'll remember that next time. It really was a pain in the **se. I printed off like 12 pages (in black and white with normal paper) before I got it right.
